The idea of making this homemade product is to facilitate the task of those craftsmen who often perform work related to cutting and processing metal products. This device is useful both in the home workshop and in the garage.
To make a desktop eccentric clamp for fixing blanks with your own hands, you will need: a profile pipe (30x20 mm and 40x25 mm), a strip segment 25 mm wide, a blank 30 mm, a pipe ¾, a spring, a stud with a diameter of 12 mm, and steel sleeves, nuts and washers.
We cut out two sections of a length of 22 cm from a profile pipe of 30x20 mm, and from one that has a section size of 40x25 mm, we cut two pieces of 2.5 cm each.
We drill through holes in them with a drill with a diameter of 8 mm, with a slight shift from the center. Then cut off the part of the profile where the hole is shifted up. Round off the edges.
Eccentric Clamp Making Process
We put these blanks on long pipes and drill holes so that after joining they can move, adjusting the tool to the workpiece clamped for processing. We fasten everything with bolts. We install a sleeve on the hairpin, securing it on both sides with washers and nuts, and weld them.
We weld the sleeve and the clamping jaws together, and we weld two bushings to them, on which the spring will be worn. Next, from the 30th disc, you need to cut a piece 22 mm long, and make a hole 8 mm displaced to the edge. We make a hole of the same size at the bottom of the homemade product.
From the pipe ¾ we cut out 20 mm for making eccentric cups. Weld them on top. Take 200 mm from the strip, cut it into two parts, make mounting and adjustment holes. Now add a pen from the rod. To enhance the capture of sponges, use the rest of the file.
Let's give an aesthetic look, a little grease the cups with lithol, and the clamp is ready to go! It very firmly fixes the workpieces, simple and convenient to use.
